신적 폭력과 역사의 구원

김기명(Kim Ki-Myoung) 한국신학연구소 2010 신학사상 Vol.0 No.151

소위 ‘민주정부’ 10년의 경험 끝에 도래한 이명박 정부 하에서 우리는 촛불집회와 용산참사라는 커다란 ‘질문’을 만났다. 신학이 단지 교회라는 종교집단의 자기 해명의 담론이 아니라면, 우리는 이 질문 앞에서 응답해야만 할 것이다. 이러한 신학적 응답을 위해 이 글에서는 20세기 초엽에 세속적 ‘정치신학’에 대한 성찰을 본격적으로 열었던 발터 벤야민(과 칼 슈미트)을 검토하려 한다. 이 글의 전반부에서는 폭력과 주권에 대한 논의를 중심으로 슈미트와 벤야민의 정치신학을 각각 ‘주권자의 정치신학’과 ‘메시아의 정치신학’이라는 이름으로 정식화하여 비교해 보려 한다. 그리고 후반부에는 신적 폭력의 논의와 결부된 벤야민의 역사의 구원에 대한 탐구를 다루어 볼 것이다. 칼 슈미트의 “정치신학”은 주권개념을 비상사태에 근거를 지운다. 주권자는 비상사태를 결정하는 자이다. 평화 시에도 주권자가 자신의 주권을 주장할 수 있는 이유는 그가 언제든지 비상사태를 선언할 수 있는 자라는 점에 있다. 주권자는 곧 세속의 ‘신’인 것이다. 벤야민은 슈미트의 정치신학의 논의를 깊이 성찰하고 받아들였지만, ‘역사’에 대한 사유를 통해 그것을 넘어선다. 억압받고 있는 자에게 비상사태는 상례이다. 그들에게는 매일의 삶이 예외적이고, 평화를 누리지 못하는 삶인 것이다. 때문에 벤야민의 과제는 이 상례화된 비상사태에 상응하는 역사의 개념에 도달하는 것이며, 그것은 곧 진정한 비상사태를 도래시키는 것으로 나타났다. 이를 위해 벤야민은 하나의 메시아적 개념이라 할 수 있는 “역사의 변증법적 이미지”를 통해 그의 정치신학을 전개한다. In the opening of the 20th Century, the seculized political theology reached the point of its culminaiton by Carl Schmitt and Walter Benjamin. The first part of this thesis will compare and contrast the political theologies of schmitt and benjamin, especially related to the sovereign and the messiah, respectively. And the latter part will be focused on the examination of benjamin' s concept of the ‘salvation of history’coupled with divine violence. Schmitt bases his concept of the sovereignty on the state of emergency. Because the sovereign is who determines the state of emergency, he has capability of his sovereignty in ordinary times as well as in the state of emergency. In this respect, the sovereign is the secularized God. Even though Benjamin accepted and considered Schmitt’s thought seriously, he overcame that through the concept of the hi story of the oppressed. According to Benjamin, the tradition of the oppressed teaches us that the ‘state of emergency' in which we live is not the exception but the rule. Therefore, Benjamin realized that is his task to bring about the real state of emergency. For this purpose, he presented hi s political theology through the thought of “the dialectical images" that is a Messianic concept.

Ki Myoung Song(송기명),Wanjae Kim(김완재) 대한기계학회 2017 대한기계학회 춘추학술대회 Vol.2017 No.11

In this paper, very large computation was done to closely capture and present some of aerodynamic details of cooled gas turbine blades. For geometry side, highly complicated real world geometry of cooled turbine blade is modeled without any simplification. For grid and solution side, very thin first layer of 10<SUP>-4</SUP>mm was generated with smooth grid transition to the core region to adequately resolve near wall flow behaviors. From the result, firstly, rather complex flow features near end-walls and blade tip are clearly visualized and explained. Secondly, the results were further compared with those obtained from two dimensional CFD model and oversimplified three dimensional models.

A Comparative Study on Flow Physics of Cooled and Uncooled Gas Turbine Blades using Numerical Method

Ki Myoung Song(송기명),Wanjae Kim(김완재) 대한기계학회 2017 대한기계학회 춘추학술대회 Vol.2017 No.11

To better understand highly complex flow features around gas turbine cooled blades, a numerical study that compares some of flow physics in rotating cooled and uncooled blades was done. Very fine grid system of over 520M cells which contains every heat enhancement feature such as rib turbulators, trailing edge slot arrays as well as cooling holes is used for the cooled gas turbine blade CFD analysis and for the uncooled blade, the same surface and volume grid quality are maintained. Vortices along with other essential flow variables were calculated and visualized using the Reynolds- Averaged Navier-Stokes equation closed by 2 equation K-w SST turbulence model. Primary and secondary vortices were observed both in cooled and uncooled CFD results however, vorticity in cooled blade overwhelmed in almost every flow region over that of uncooled blade due to high speed cooling flow discharge and mixing.

지능과 창의성 수준에 따른 학업 성취 및 성격 특성 비교

이신동(Lee Shin dong),김기명(Kim Ki myoung) 한국영재교육학회 2006 영재와 영재교육 Vol.5 No.2

  본 연구는 지능과 창의성의 수준에 따라 학업성취와 성격특성에 어떠한 차이가 있는지를 알아보고 이를 비교하기 위한 것이다. 이를 위해 초등학교 2곳의 6학년 남녀 학생 151명을 연구 대상으로 하였으며, 지능 검사ㆍ창의성 검사ㆍ학업성취 검사ㆍ성격특성 검사의 자료를 수집ㆍ분석하였다. 검사도구로는 유기섭ㆍ이기우(2002)가 제작한 기초지능검사, 김영채(1999)가 편역한 한국판 TTCT검사, 이상로ㆍ변창진ㆍ진위교(1996)가 표준화한 성격진단검사, 2005학년도도 학력평가를 활용하였다. 본 연구의 결과 고지능 집단이 보통 지능 집단보다 높은 수준의 학업성취 및 성격 특성 수준을 나타내었으나, 고창의성 집단과 보통창의성 집단 간에 학업성취에서 유의한 차이를 나타내지는 못하였다. 지능과 창의성 수준에 따른 학업성취 수준에서는 고지능-고창의성 집단이 수학교과에서 높은 것으로 나타났으며, 국어, 사회, 과학, 전체학업 성적은 고지능-보통창의성 집단이 높은 것으로 나타난 반면에 지능과 창의성의 수준에 따른 성격특성에서는 유의한 차이를 나타내지 못하였다. 이런 결과는 학업성취를 측정하는 문항들의 논리적 사고력 편중과 확산적 사고의 부족, 성격특성이 지능ㆍ창의성과 어떠한 관련성이 있는지에 대한 무관심 등에서 찾을 수 있겠다. 따라서 이러한 문제를 해결하기 위해서는 학업성취 측정 문항을 세분화하고 종합적 사고능력을 측정할 수 있는 평가 문항의 개발과 아울러 그 동안 성격특성이 지능과 창의성을 적절히 설명해주고 있지 않다고 하여 이를 간과하기 보다는 이들 간의 관계를 규명하고 이를 교육적으로 활용할 수 있는 방안을 모색하기 위한 심층적 노력이 요구된다   This study examined the difference between the academic achievement and personality traits by intelligence and the level of creativity and compared those things.<BR>  The subjects of this study were 151 of boys and girls in 2 elementary schools and we collected and analyzed the data of intellectual examination, creativity examination, academic achievement examination and character examination of 151 students. The test tools were the Basic Intellectual Examination copy produced by Lee Gi Woo and Yoo Gi Seop (2002), the Creativity Examination of Torrance for the standardized creativity test edited by Kim Young Chae (1999), the 2005 provincial scholastic ability test, and the character diagnosis test survey standardized by Lee Sang Lo, Byun Chang Jin and Jean Wee Gyo (1996) for personality traits. The result of this study, high-intelligence group showed higher level of academic achievement and personality traits than normal-intelligence group but a significant difference between high-creativity group and normal-creativity group was appeared. In the level of academic achievement by intelligence and creativity, high-intelligence-high-creativity group showed higher level of the attainment in Math. And high-intelligence-normal-creativity group had higher grade in Korean, society, science and whole records but in personality traits by the level of intelligence and creativity, high-intelligence-high creativity group showed higher tendency in sociality and responsibility was not significant. Those results can be found in the indifference of how the items measuring the academic achievement relate to the question items biased toward logical thinking ability, the lack of extensive thinking faculty, and personality traits etc. Consequently, to solve this problem, the items for academic achievement measurement should be specified and the test items that comprehensive thinking ability can be measured should be developed. In addition, it needs to make a deep effort to clarify the relationship between those problems and to find the way which can use those in educational situation rather than overlook the problems because of the fact that personality traits can"t explain relationship to both intelligence and creativity.

초등학교 수학영재, 과학영재, 일반 학생의 학습유형 및 교수방법 선호도 비교

이신동(Lee Shin Dong),원재권(Won Jae Gourn),김기명(Kim Ki Myoung) 한국영재교육학회 2007 영재와 영재교육 Vol.6 No.2

본 연구는 Kolb의 4가지 학습유형에 따라 초등학교 수학영재, 과학영재, 일반 학생의 학습유형을 비교해 보고, 학습유형에 따라 교수방법 선호도가 어떻게 달라지는지 확인하기 위한 것이다. 이를 위해 지역교육청 2곳의 영재교육원 초등학교 수학ㆍ과학영재 학생 각60명, 일반 학생은 초등학교 2곳의 6학년 120명 총 240명을 연구 대상으로 하였으며, 이들의 학습유형검사ㆍ교수방법선호도 검사의 자료를 수집ㆍ분석하였다. 검사도구로는 Kolb(1999)의 학습유형검사(LSI), Renzulli, Rizza, & Smith(2002)의 교수방법 선호도 측정 검사지를 활용하였다. 본 연구의 결과 수학영재 학생과 과학영재학생의 학습유형은 차이가 없었으나 영재학생과 일반학생의 학습유형에는 차이가 있었으며, 동화적 학습자 유형을 제외한 발산적 학습자, 수렴적 학습자, 조절적 학습자 유형은 고유하게 선호하는 교수방법들을 가지고 있었다. 또한 수학영재 학생과 일반학생은 학습유형에 따른 교수방법 선호도에 차이가 없었으나, 과학영재 학생은 학습유형에 따fms 교수방법 선호도가 다르게 나타났다. 이런 결과는 영재학생과 일반학생의 학습유형이 서로 다르고 그에 따른 교수방법도 다르다는 것을 나타낸다. 따라서 교실수업을 담당하는 교사들은 학생들의 학습유형에 맞는 교수방법을 제공하여 교수적합성을 달성함과 동시에 교수 효과를 극대화하기 위해서 각각의 학습유형과 교수방법에 대한 충분한 이해가 선행되어야 할 것이다. The purpose of this study is to compare the learning styles of the mathematics gifted, the science gifted, and general students at elementary schools by Kolb"s four learning styles, and ascertain how the preference of instructional methods become different by learning style. To achieve the purpose in this study, the four propositions were set as follows: First, what differences exist among the mathematics gifted, the science gifted and general students in terms of learning style? Second, what differences exist in terms of the preference of instructional methods by learning style among the mathematics gifted, the science gifted, and general students? To solve the abovementioned propositions, this study targeted 60 elementary school-level mathematics gifted students, 60 science gifted students at gifted students education institutes, and 120 six graders at Elementary School: this study targeted a total of 240 students. For the learning style test used in this study, ""Learning Style Inventory (LSI),"" which originally presented by Kolb in 1976, but was revised anew in 1999, and was translated by Lee, Shin-dong (2005), was used. As a test to measure the preference of instructional methods, ""Measure of Student Preference for Instructional Techniques,"" developed by Renzulli, Rizza, and Smith (2002), and translated by Lee Shin-dong (2005) was used. The confidence levels of the tests were good, respectively. The analysis of the collected test responses was tested through a confidence analysis, technical statistics, MANOVA, and Sheffe test was used for follow up test. The SPSS 12.0 Program was used for the analysis. The analytical results of the collected data are presented as follows: Firstly, there was no difference in the learning style of the mathematics gifted and the science gifted, but there was difference in the learning style of the gifted and general students. Secondly, it was identified that divergent learners, convergent learners, regulated learners, except for assimilative learners, had their preferred instructional methods. Thirdly, there was no difference in the preference of instructional methods by learning style and gender between the mathematics gifted and general students. The science gifted students had different preference of instructional methods by learning style, but they did not show any difference on the preference of instructional methods by gender. In conclusion, the divergent learners and convergent learners are judged to be more active in learning activities and have higher learning motivation. Teachers taking charge of classroom teaching should provide instructional methods in line with such learning styles so as to achieve the adequacy of instruction, and draw maximum instructional effects. Those teachers also need to pay more attention to enhancing learning motivation of the relatively passive regulated learners and assimilative learners.

CA 19-9의 현저한 상승을 보인 간내담관낭선종 1예

김병하,임창영,신현덕,송일한,신정우,기명주,김정택,노임환,이재현 대한소화기학회 2001 대한소화기학회지 Vol.37 No.3

Hepatobiliary cystadenoma is a rare but distinct neoplasm with malignant potential. The differential diagnosis includes other cystic neoplasms, primary or metastatic, and nonneoplastic cysts including infective conditions. A 38-year-old woman was admitted because of abrupt epigastric pain. Abdominal imaging studies revealed about 15×10 cm sized multiloculated cystic lesion in left lobe of the liver. Both serum and cystic fluid level of CA 19-9 were raised above 2,400 U/mL. Laparotomy and left lobectomy were performed. A 15×10 cm sized cystic mass was noted in left lobe of the liver. About 1,800 mL of serous fluid was obtained from this multiloculated cystic mass. Microscopic findings revealed a cystadenoma lined by a single layer of columnar epithelium containing some intracellular mucin pools and hemorrhagic infarct without evidence of cellular atypism or mitosis. We report a case of intrahepatic biliary cystadenoma with markedly elevated CA 19-9 with the review of literatures.

학문적 재능에 영향을 미치는 관련변인들 간의 구조적 분석을 통한 Gagne의 DMGT 2.0 모형 검증

김기명,이신동 안암교육학회 2012 한국교육학연구 Vol.18 No.1

The purpose of this research is to empirically verify the Structural Model of the Variables on Academic Talent Based on Gagne's DMGT 2.0 Model. To achieve this purpose, in this research I attempted to analyze structural correlations between the research models established based on the Gagne’s DMGT model and related preceding models and the Alternative Models. In order to conduct this research, students in the 1st year of special purpose highschools were chosen as subjects. The results of this research are summarized as follows. First, this research could prove that differentiated recognition of giftedness and talent independently was valid. Second, this research presents the grounds for why the special education for the gifted is needed by showing that the individual internal variables and the environmental variables exert great effects on the learning process as the giftedness is expressed as the talent. This results could provide basic data to establish correlation between giftedness and talent and to define giftedness. Also, This results presents the grounds for why the special education for the gifted is needed. 본 연구는 학문적 재능에 영향을 미치는 관련변인들에 대한 구조적 분석을 통해 Gagne(2010)의 DMGT 2.0 모형을 경험적으로 검증하는데 그 목적이 있다. 이를 위해 Gagne(2010)의 DMGT 2.0 모형 및 관련 선행연구를 토대로 연구모형 및 대안모형을 설정 하고, 이들 구조 모형에 대한 적합도 검증 및 구조적 분석을 실시하였다. 과학고와 외고 피 험자를 대상으로 수행된 연구모형 및 대안모형에 대한 구조적 모형 검증 결과, Gagne(2010)가 DMGT 2.0 모형에서 제시하고 있는 영재성과 재능에 대한 차별적 인식이 매우 타당한 것으로 나타났으며, 영재성이 학문적 재능으로의 발달과정에서 학습과정에 미치 는 개인내적.환경적 변인의 영향력이 상당히 큰 것으로 드러났다. 이를 통해 본 연구는 영 재성과 재능의 관계 정립 및 영재 정의를 위한 기초 자료를 제공함과 동시에 영재교육이 왜 필요한지에 대한 근거도 함께 제시하고 있다.

긴장성 기뇌 1례

소병학,박승현,김기명,김세경 대한응급의학회 2002 대한응급의학회지 Vol.13 No.2

This paper presents one case of subdural tension pneumocephalus which deteriorated in the early phase of head trauma. Pneumocephalus occurs in 0.5 to 1.0% of head trauma cases. Most patients have nonspecific signs and symptoms, such as headache. Therefore, a high index of suspicion in a patient with recent head trauma is necessary. Therapy is often noninvasive, allowing the craniodural defect to heal spontaneously. However, if enough air collects within the cranium or the brain itself, a mass effect with marked midline shift may develop. This is referred to as tension pneumocephlus and may result in herniation symdrome. Prompt decompression is essential.
